Proximal tubule: The simple cuboidal cells of the proximal tubule are called _______ cells

Answers

Answer:

brush border cells....!!

Final answer:

The simple cuboidal cells of the proximal tubule are referred to as Proximal Convoluted Tubule (PCT) cells.

Explanation:

They have a distinct feature of having prominent microvilli on their luminal surface that forms a brush border.

These microvilli contribute to creating a large surface area which facilitates the maximization of the absorption and secretion of solutes including Na+, Cl¯, glucose, among others - a key function of this portion of the nephron.

These cells are responsible for the active transport of ions across their membranes and hence they possess a high concentration of mitochondria to produce sufficient ATP.

The PCT cells, forming a simple cuboidal epithelium, are active in secretion and absorption of molecules.

They are observed in the lining of the kidney tubules and are critical to the kidney's filtration function.

Dichotomous Key for Animal and Plant Cell, this is a kind of messy key, but it will give you an example of what to do. You're Welcome!
If you need more help with cytology, just ask me, I'm a A+ in Biology. 
1. Has a cell wall                                                           Go to number 2
    Has no cell wall                                                          Go to number 3
2. Has a central vacuole                                                Go to number 4
    Has no central vacuole                                        Than it can't be a plant or animal cell
3. Has a cell membrane                                                  Go to number 5 
    Has no cell membrane                                All eukaryotic cells have a cell membrane
4. Has chloroplasts
Has to be a plant cell because it has a cell wall, a central vacuole and chloroplasts 
    Has no chloroplasts                                     Than it can't be a plant or animal cell
5. Has a nucleus                                                          Go to number 6  
    Has no nucleus                                            Than it can't be a plant or animal cell
6. Has more than one lysosome                    Has to be an animal cell because it has no cell wall or central vacuole or chloroplasts and it has more than one lysosome. 
   Has only one lysosome                                    Plant cells only have one lysosome

"Windrow composting is a process whereby compostable materials are fed into an environmentally controlled enclosed structure and allowed to decompose over time."A. True
B. False

Answers

Answer:

B. False

Explanation:

Windrow composting is the process to recycle organic scrap into organic fertilizer. Windrow composting provides large amounts of organic materials to be composted, having a geometrical pattern ranging from 2-4 m wide and 2-3 m high at the starting of the Windrow composting process. In Windrow Composting the most important thing is that it delivers water vapor, heat, and gases, and restores also.

Natural selection acts by taking advantage of natural variations in the traits of organisms within a population what is the ultimate source of this variation

Answers

The answer is the mutations within the genetic code. 

Natural selection is one of the basic mechanisms of evolution by which species adapt to their environment in order to increase their chance of survival and reproduction. In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. But, the sources of this genotype variations are not changes in the environment, nor response to the stress, but the mutations in the genome of the organism. If a mutation is not lethal, it could remain in the population, increasing the variation is some traits.
